SHOE HEEL ANI) SOLE LIFT.

Application filed March 12, 1924. Serial No. 698,618.

To all 'whom it may concern:

Be it known that I, RUDOLPH C. G. STAATS- OELs, a citizen of the United States, residing at Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Shoe Heel and Sole Lifts, of which the following is a specification. i

This invention relates to lifts for the sole and heel of shoes, and hasfor its main -object to provide means, simple in construction, effective in operation, and durable in use, adapted to give a resilient tread to the entire dorsal surface of the foot or the heel or ball thereof.

A further object of the invention is to provide a resilient heel and sole lift that is not only resilient, but also pneumatic, and in which air is confined to provide a cushioning effect, and in which the inherent resilience of the material forming the lift is supplementedl by the cushioned air within the lift. l

Another object of the invention is to pro-` vide a device of the class described which not only contains air, but also contains air under initial compression, whereby the cushioning effect is constantly maintained to a maximum extent.

lVii'h the foregoing, and other objects in view, hereinafter stated, the invention consists of the novel construction, combination and arrangement of parts hereinafter more specifically stated, and illustrated in the accompanying drawings, wherein is shown a device embodying the structure `of the invention in its preferred form, but it is to be understood that changes, variations and modifications may be resorted to without departing from the scope of the invention.

.ln describing the invention in detail, reference is had to the accompanying drawings, which form a part of this specification, and wherein like characters of refer ence indicate corresponding parts throughout the several views, and wherein:

Fig. l is a vertical sectionof a heel lift embodying` the invention in one of its forms as arranged when applied to a shoe cated in detted lines Fig. 2 is a vertical section of the parts forming the heel lift shown in Fig. l, an ranged in partial engagement with each other.

Fig. 8 is a plan of the tread surface of the lift shownA in Fig. 1.

Fig. l is al plan view, partly broken away, of a sole liftembodying the invention.

Fig.- 5 is a longitudinal central section of the sole lift, shown inFig. t, partly broken away, and "t Fig. 6 is a fragmentary section of the outer margin andv connecting portion of a lift, embodying a modification of the invention.

l As illustrated in the drawings the heel lift is constructed of an attaching section l and a tread section 2. The section l is provided with a marginal flange 3, offset from the margin of the section, and engaging a marginal flange fl of the tread section 2, and a step 5, on the outer margin of the tread section, said flanges together forming the outer wall of the lift. Y

The flat bearing surfaces of the sections are spaced from each other intermediate the outer wall. and are provided with complementary bosses, 6 and 7, which bear against cach other at their ends, as shown in Fig. l, fornling bearings between the flat surfaces of said members intermediate the outer margins thereof and at the same time maintaining a hollow chamber intermediate th sections.

The ends of the bosses are preferably con` strueted to engage each other and to that end one of the bosses 7 is recessed as at 8 to provide means for engaging the end of the opposite section 6,

Recesses 9 are formed in the flat bearing surfaces and in the bosses of the attaching section to a point removed from the end thereof, and corresponding recesses l0 are formed in the tread section, which isalso provided with a recess l1 for the insertion of the head of a nail.

lVhen the parts are so constructed, the attaching section or male member of the heel is brought into engagement with the tread or female section, by bringing the margin of the flange 3 int@ engagement with,

that of the flange -1- as shown in Fig. 2. The air then conlined between the two sections is compressed to a limitedv extent, as the two sections are brought together as shown in Fig. 1.

The .side walls of the .sections when brought together `are cemented together, and are firmly secured by the ext-ended bearing and holding surfaces comprising'the side and end surfaces 4ofthe engaging 'flanges From the foregoing description, taken in connection with the drawings, the construction, operation and advantages of the heel lift will clearly appear.

lt will be .seen that a lili-t is provid-'ed that may be vmade of resilient mater-ital, preterably rubber and that the lift is provided with an air chamber so constructed that .air is 4eli-trapped within the chamber, while 'the sections of the lift Aare l'bei-ng brought into enga-gement with each other, and is maintained within said chamber under s-uliicient pressure to maintain the litt in an int-lated con-dition, thereby giving to the user not only the benefit of the inherent vresiliency of the rubber material forming the body of the litt, but also the benefit Aof the vair cushion termed in the lift-t.

The invention as embodied in a sole litt ifs shown in Figs. 4 and 5, in which the lift is constructed ot .an :attach-ing section 12 and a tread section 13.

As shown i-n Fig. 5 the attaching section 1-2 is provided with ainarginal rib 14, which engages a. corresponding recess formed in the .adjacent part fot the tread member 13., to torni .a locking engagement between said sections. v

Means may be provided of lany suitable construction for limiting the movement 'of the tread :surface 12, relative to the attaching section.

In `the drawings :such means consist of transverse ribs 15 and connecting' ribs 16. rlfhe upper surface of said ribs being preterably .but not essentially arranged in the. plane ol the outer surface off the. ribs 141.

The sections of the sole lift are brought together ina manner similar to the sections of the heel lift. As the outer margin ol the rib 14E comes in contact with the wall of the recess in the tread section, a certain amount of air is confined within the hollow interior of the litt and when the outer walls of vthe sections are cemented together, the air is maintained within said interior, and is compressed to a limited extent, causing ory tending to ycause fthe tread surface :of the lift .to bulge slightly outward, `as indicated by the dotted line in Fig.. 5.

As illustrated in Fig. 5 the outer margin of the tread section is reduced by means `of a marginal recess or step 16, formed thereon. That is not an essential `feature oi the invention, however, `and if desired, the outer margin of the tread sect-ion may be made flush with the tread surface of the section as shown in Fig. 6.

Where the outer margin of the tread sectionis reduced as shown in Figs. 4- and 5, the toe `end .of the lift may be ,provided with a. wearing plate 17, which may be set into and secured to the reduced marginal toe portionotthe lift, by means oft nails 18 'or otherwise.

The lift Amay be secured to the sole of a shoe by means of a` row of stitching along the outer vmargin ot' the lift, or by other means, and tor some purposes the lift may be used as the sole of :a shoe.

By means such -constructi'r-m, a lift or sole is provi ed rthat is simple and strong in structure, and durable in use 4and which provides fa seit yielding tread 'for the foot, and avoids the heating effect produced by heavy rubber soles, for the reason that the air cushion prevents heat from being .transinittedjto the foot of the userin the summer time.

Such Aconstruction also .prevents cold rtroin passing :to the ico-t of the user in 'the winter time, the Aair `:cushion serving as non con- -Cluctoin ln the constructions shown in Figs. 1 and 2, bosses 'are formed on both the attaching and tread sections. Such construction may be' modi-fied it desired', and the bosses lier-ined 'ononeoi'' the sections only as shown in Fig. 5.

In the constructionshown in Fig. -5, moreover, the ribs 15 and y16 Amay normally` be extended so as to be in close proximity to the inner surface ci tlietread section.

Instead of the ribs 15 `and 16, shown in Figs. l and 5, bosses similar to those indicated Figs. 1 land V2 or modifications thereof may be used.

Thile the heel lit-t shown herein as made. independently of the. sole lift, that is not an essential :feature of the invention and if 'desired both oi said lifts may be made integr-al with each other.

`In Figs. l1 1and 2 the bosses, when in contact, 4are* of substantially the same length. In somey cases, however, it is preferable to make the bosses ot the male section 1 longer than those ot the fem-alc section 2, so that. bosses ot the male section may engage the bosses of the female section the `same time the marginal flange S, of the' male section engages the marginal flange Il of the female .section 2, and when so constructed the vopenings 9 'of the bosses for the attaching nails may be forme-d entirely through the bosses. f

What I claim as new and desire to secure by Letters Patent, is:

1. A resilient lift for heels` comprising complementary sections provided with marginal flanges cemented together and having on their inner faces engaging bosses provided with closed ends and with nail apertures extending from said closed ends to the outer surface of said sections.

2. A resilient lift for shoes having complementary sections pro-vided with engaging side walls cemented t0gether,'one of said sections having a plurality of bosses provided with a nail aperture and a closed end, said sections and walls forming an air chamber within said lift.

3. A resilient lift for heels including complementary sections capable of engagement at their outer margins and recessed in their adjacent `faces to provide an air chamber interiorly of said lift, and bosses extending` from said faces into engagement with each other, said bosses having closed ends and apertures extending outwardly from said ends.

l. A resilient lift for heels including complementary sections capable of engagement at their outer margins and recessed in their adjacent faces to provide an air chamber interiorly of said lift, bosses extending from said faces into engagement with each other, said bosses having closed ends and apertures extending outwardly from said ends7 and one of said bosses having a recess into which extends a portion off the other boss when the bosses are enga-ged.

In testimony whereof I have afxed my signature.
